Underlayment Options:

Standard Flexamat® is manufactured with the Aspen wood excelsior, Curlex II®.
(view more information about Curlex® Blankets)  This underlayment helps encourage vegetation growth. Click here to download Product Data Sheet for Standard Flexamat®.

Flexamat® Plus is manufactured with Recyclex® TRM (view more information about Recyclex® TRM) underlayment is used when a permanent backing is needed.  This product is made from recycled soda bottles (nylon fiber that will not float).  This backing will allow vegetation growth and will remain permanently as an underlayment if growth isn't present.  This backing is used primarily in arid environments, areas susceptible to drought, areas with poor soils, and shaded areas.  Click here to download Product Data Sheet for Flexamat® Plus.

Flexamat® may also be manufactured with non-woven fabrics underlayment. This backing is used in instances where not possible or not desired.  Non-woven backings should be used for areas exposed to continuous flows or where sandy soils are present.  Fabrics are also used when Flexamat® is installed over plastic liners. The fabric provides a protective barrier between the liner and the concrete blocks. Project requirements determine the fabric used, Flexamat® can be manufactured with a wide range of non-woven fabrics.  Click here to download Product Data Sheet for Flexamat® with filter fabric.

Flexamat® may also be manufactured without underlayment backing, consisting of just the concrete blocks and the interlocking Geogrid.  This option is available for projects that require unique underlayment or instances where Flexamat® is installed over existing turf.

Interlocking Geogrid Options:
Flexamat® Standard and Plus:  

Fornit 30-30-35 polypropylene bi-axial geogrid - used in all Flexamat® products unless specifically noted. The bi-axial gregrid has tensile strength of 2055lbs and is UV stabilized. This geogrid was selected after years of research and field testing. Polypropylene geogrid is not adversely affected by the high pH environment encountered when embedding the grid within wet concrete. (Polyester yarns degrade when exposed to uncured, wet concrete having a pH of approximately 11.5.)

Flexamat® FR:

Flame Resistant Geogrid - a bi-axial geogrid with flame-resistant coating.  This material is used on Flexamat® projects in areas where wildfires or controlled prairie burns are anticipated.

Flexamat® Basic

Polypropylene geogrid – low cost bi-axial geogrid used in applications where the long-term integrity of the interlocking geogrid is not critical.

Optional Cores:

Flexamat® can be manufactured with cores within the rolls. A variety of custom core options are available.
